Abstract
The invention is directed to stabilizer compositions, to polymers containing three stabilizer compositions for use as additives in polymers, and to polymeric products which contain these additives. The stabilizer compositions comprise a compositon of: a) at least two hindered phenols and b) a sulfide. These compositions are admixed with polymers to provide polymeric additives to improve the physical and mechanical properties of polymers matrices.
